Sun Fire V240 Server: Power Supply Unit
Removal
Power supply units on the Sun Fire V240 server cannot be removed from the server
until the power cable has been disconnected from the inlet socket.
When disconnecting a power cable from a PSU inlet socket, make sure you are
disconnecting from the PSU you intend to remove from the server.

Air Duct

The design of the air duct inside the server has changed since the platform
documentation went to print.
The air duct no longer screws into place, as described in the Sun Fire V210 and V240
Servers Parts Replacement Manual, but clips into the chassis instead. Use the handle on
top of the duct to position it correctly and clip it into the chassis.

Replacing the System Board

The CPU and System Board Assembly section of the Sun Fire V210 and V240 Servers
Parts Replacement Manual has one step missing:
Before unscrewing the DB-9 and SCSI jackposts (step 11), remove the CPU
heatsink(s).
For instructions on how to do this, refer to the "CPU Heatsink Assembly" section of
the Sun Fire V210 and V240 Servers Parts Replacement Manual.
When installing a system board, replace the CPU heatsink(s) before reconnecting
the system board cables (step 6).
